[0009] FIG. 2 is a perspective view the first preferred embodiment of the present invention.

[0010] FIG. 3 is an exploded view of a second preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Referring to FIGS. 1 and 2, a housing 10 in accordance with the first preferred embodiment of the present invention is composed of a bottom shell 20, an upper cover shell 30, and a lower cover shell 40.

[0012] The bottom shell 20 includes an upright base panel 21, which is formed of an upper part 22, a lower part 23 spaced below the upper part 22 at a distance, a connecting part 24 vertically connected between the upper part 22 and the lower part 23 at a lateral side (the left side as shown in FIG. 1), and a peripheral wall 25 perpendicularly inwardly extending along a border of the base panel 21. The upper part 22 of the base panel 21 has two top corners respectively beveled (the upper left corner) and chamfered (the upper right corner). The peripheral wall 25 and the base panel 21 define a receiving space 26 adapted to accommodate a drive wheel (not shown) and a driven wheel 52. It is to be noted that the aforesaid drive wheel and driven wheel and the other parts of the band sawing machine, such as band saw, worktable, motor 54, switch 56, a band saw lock 58, and so on, are not within the scope of the invention, and therefore no further detailed description in this regard is necessary.

[0013] The upper cover shell 30 includes an upright base panel 31, which is formed of a main body 32, a bottom extension 33 extending downwardly from a bottom side of the main body 32 at a lateral side (the left side as shown in FIG. 1), and a peripheral wall 35 perpendicularly extending along a border of the base panel 31. The main body 32 of the base panel 31 of the upper cover shell 30 fits the upper part 22 of the base panel 21 of the bottom shell 20. The bottom extension 33 defines a connecting side edge 34 at a bottom end thereof and the connecting side edge 34 has an opening 36. The upper cover shell 30 is covered on the upper part 22 of the bottom shell 20, keeping the peripheral wall 35 of the upper cover shell 30 approaching the peripheral wall 25 of the bottom shell 20 (see FIG. 2). According to this embodiment, the upper cover shell 30 is fastened pivotally with the peripheral wall 25 of the bottom shell 20 by a hinge 37 at a lateral side thereof, namely, a left side adjacent to the connecting part 24 in FIG. 1. Thus, the upper cover shell 30 can be turned relative to the bottom shell 20 to expose the inside of the bottom shell 20. A lock 11 is provided at the other side, namely, the right side in FIG. 1, and adapted to lock the upper cover shell 30 together with the upper part 22 of the bottom shell 20. The lock 11 is composed of a bolt 12 fastened pivotally with the main body 32 of the base panel 31 of the upper cover shell 30 at the right side, and a retainer 13 mounted on the bottom shell 20 adapted to receive the bolt 12. When the upper cover shell 30 is covered onto the upper part 22 of the bottom shell 20, the bolt 12 is forced into the retainer 13 and secured in place by the retainer 13. After the upper cover shell 30 is covered onto the upper part 22 of the bottom shell 20, the user can pull the bolt 12 and then open the upper cover shell 30.

[0014] The lower cover shell 40 includes a base panel 41, which is formed of a main body 42 and a top extension 43 upwardly extending from a top side of the main body 22 at a lateral side (the left side as shown in FIG. 1), and a peripheral wall 45 perpendicularly extending along a border of the base panel 41. The main body 42 of the base panel 41 of the upper cover shell 40 fits the lower part 23 of the base panel 21 of the bottom shell 20. The top extension 43 has a connecting side edge 44 a top end and the connecting side edge 44 defining an opening 46. The lower cover shell 40 is covered on the lower part 23 of the bottom shell 20, keeping the peripheral wall 45 of the lower cover shell 40 abutted against the peripheral wall 25 of the bottom shell 20 (see FIG. 2). According to this embodiment, the lower cover shell 40 is fastened pivotally with the peripheral wall 25 of the bottom shell 20 by a hinge 47 at a lateral side, namely, the left side adjacent to the connecting part 24 in FIG. 1. Thus, the lower cover shell 40 can be turned relative to the bottom shell 20 to expose the inside of the lower part 23 of the bottom shell 20. A lock 14 is provided at the other side, namely, the right side in FIG. 1, and adapted to lock the lower cover shell 40 together with the lower part 23 of the bottom shell 20. When the upper cover shell 30 and the lower cover shell 40 are covered onto the bottom shell 20, the connecting side edges 34 and 44 are abutted against each other, and the base panels 31 and 41 of the upper and lower cover shells 30 and 40 fit over the base panel 21 of the bottom shell 20.

[0015] FIG. 2 illustrates the housing 10 installed a band sawing machine 50. As indicated above, the upper cover shell 30 and the lower cover shell 40 are respectively hinged to the bottom shell 20. While examining or repairing machine parts in the upper part 22 of the bottom shell 20 (for example, the driven wheel 52) or in the lower part 23 of the bottom shell 20 (for example, driving mechanism), it's as easy as opening the upper cover shell 30 or the lower cover shell 40.

[0016] Further, the bottom shell 20, upper cover shell 30, and lower cover shell 40 of the housing 10 are respectively made of a metal sheet by stamping so as to have advantages of easy fabrication and low manufacturing cost.

[0017] In the aforesaid first embodiment, the upper cover shell 30 and the lower cover shell 40 are symmetrical, i.e., the base panel 31 of the upper cover shell 30 and the base panel 41 of the lower cover shell 40 are combined together to fit the shape of the base panel 21 of the bottom shell 20. Alternatively, the upper cover shell 30 and the lower cover shell 40 can be made in different shapes. For example, one of cover shell 30 and 40 can be made relatively bigger than the other one, and the bigger cover shell 30 or 40 covers over the connecting part 24 of the bottom shell 20. In any alternate form, the upper cover shell 30 and the lower cover shell 40 are combined together to fit the shape of the bottom shell 20.

[0018] Referring to FIG. 3, according to a second preferred embodiment, the housing 60 is composed of a bottom shell 70 and a cover shell 80 covering the bottom shell 70. The bottom shell 70 and the cover shell 80 are respectively made of a metal sheet by stamping. The shape of the bottom shell 70 is the same as the bottom shell 20 of the first embodiment shown in FIGS. 1 and 2. The cover shell 80 includes a base panel 81 fitting the base panel 71 of the bottom shell 70, and a peripheral wall 85 perpendicularly extending along the border of the base panel 81. Two hinges 87 are connected between the peripheral wall 75 of the bottom shell 70 and the peripheral wall 85 of the cover shell 80 at a side corresponding to the middle connecting part 74 of the bottom shell 70, for enabling the cover shell 80 to be turned relative to the bottom shell 70 to close/open the bottom shell 70. Two locks 61 and 62 are provided at the other side for locking the cover shell 80 together with the bottom shell 70.

[0019] Because the bottom shell 70 and the cover shell 80 are respectively made of a metal sheet by stamping, the manufacturing cost of the housing 60 is low.

[0020] Moreover, the cover shells including the upper cover shell 30 and a lower cover shell 40 in the first embodiment and the cover shell 80 in the second embodiment can be alternatively not provided with peripheral walls 35, 45, 85. In other words, while the cover shell covers the bottom shell, the receiving space can still be covered by the border of the cover shell fitting against the border of the base panel.
